摘要： A detection mechanism is provided with a sealing member made of elastic material for preventing toner leakage between (a) a pierced wall surface of a toner tank through which a rotating shaft is inserted and (b) a second side plate provided on the rotating shaft. With this structure, a flat splicing surface of the sealing member is made to closely contact a second side plate that can be coated with a high lubricant member whose frictional forces is small. When a sealing force of the sealing member is strongly compressed, the sealing member prevents toner from coming into the sliding surface.

摘要： A developing unit and an image forming apparatus includes drive and control mechanisms for the conveyance of collected toner and fresh toner in an uncomplicated structure and an uncomplicated toner supplying roller structure for the reduction in manufacturing cost. Fresh toner and collected toner stored in housing parts of a toner housing are discharged from an outlet via openings formed in a partitioning member for forwarding to a developing section by a toner supplying roller disposed to confront the outlet. The toner supplying roller is provided in common to fresh toner and collected toner. The toner supplying roller includes a single rotary shaft and a plurality of composite members which are fit into the rotary shaft. Each of the composite members has a cylindrical hollow body and a cylindrical elastic body which is fit onto the outer peripheral surface of the hollow body. The composite members are disposed correspondingly to the housing parts.
